Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If battery information is uniformly provided without considering form factor changes, then the device structure is simple, but the accuracy of battery information is insufficient
Solution Approach 1:
The patent implements dynamic battery information provision by detecting form factor changes through sensors and adjusting the displayed available time based on the current mode (folding, unfolding, or custom). The processor dynamically calculates and updates battery information according to real-time device state, making the battery information adaptive rather than static.
Solution Approach 2:
The system employs feedback mechanisms where sensors continuously monitor the device's physical form factor and feed this information back to the processor. The processor then recalculates and updates the battery available time display based on this feedback, creating a closed-loop system that ensures accurate battery information reflects the actual device state.
2Measurement precision
If battery information is dynamically adjusted according to form factor changes, then the battery information accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent segments the device operation into distinct modes (folding mode, unfolding mode, and custom mode) based on the physical form factor. Each mode has predetermined power consumption characteristics, allowing the system to select appropriate battery calculations for each segment rather than using a single complex model for all states.
Solution Approach 2:
The system changes operational parameters (power consumption values) based on the detected form factor mode. The processor stores multiple power consumption parameters corresponding to different device states and selects the appropriate parameter for battery calculation, simplifying the overall system while maintaining accuracy.
3Measurement precision
If different power consumption values are used for different modes, then the battery available time calculation is accurate, but the energy management complexity increases
Solution Approach 1:
The patent pre-stores multiple power consumption values corresponding to different device modes (folding, unfolding, custom) in the processor. This preliminary preparation eliminates the need for complex real-time power consumption measurements and calculations, as the system can directly select from pre-determined values based on the current mode.
Solution Approach 2:
The processor performs multiple functions: it detects form factor changes, determines the current mode, selects appropriate power consumption values, calculates battery available time, and controls display output. This multi-functionality consolidates energy management tasks into a single component, reducing overall system complexity despite handling multiple parameters.
